A merge of the two panels shows that the spatial distribution of neurofilament 200 and TRPV2 expression overlaps. However, DRGs showing robust expression of neurofilament 200 do not contain TRPV2.

Scientific background

TRP channels are a large family (about 28 genes) of plasma membrane, non-selective cationic channels that are either specifically or ubiquitously expressed in excitable and non-excitable cells.1 The TRP channels have six putative transmembrane domains (TM) with a pore domain between the fifth and the sixth TM, and all assemble as tetramers. Both the N- and the C-termini of all TRPs are intracellular3.

According to IUPHAR, the TRP family is comprised of numerous subfamilies on the basis of sequence homology; TRPC, TRPM, TRPV, TRPA, TRPML, and TRPP1-4. The TRPV subfamily consists of six members, TRPV1-65.

Four members of the TRPV family have been described as thermosensitive ion channels (TRPV1 to TRPV4). Each channel exhibits distinct thermal activation thresholds ranging from noxious cold (<17°C) to noxious heat (>52°C) 6,7. Although it shares around 50% homology with TRPV1, TRPV2 is not activated by capsaicin nor by protons. It has a high temperature threshold of ~52°C and is considered to play an essential role in the perception of high-intensity noxious heat stimulation8-10. TRPV2 is also considered to be a stretch-activated channel and to play a role in skeletal and cardiac muscle degeneration and pain pathway8. The TRPV2 channel is expressed in DRG neurons, different brain regions and non-neuronal tissues such as the spleen, lung and intestine and in components of the immune system5,11,12.
